Be on the alert for fall armyworms this fall

From Insects in the City

Pest management professionals who care for lawns should be on the alert for fall armyworms this fall. Higher-than-normal populations of this lawn-eating insect have been reported from many areas in Texas these past two weeks.

While fall armyworms are nothing new, according to Dr. Allen Knutson, extension agricultural entomologist in Dallas, this year they are a widespread problem for hay producers and small grains producers across the state.  “I’ve had calls as far west as Wichita Falls, south to Comanche and across east Texas,” he said.  Locally in the Dallas/Fort Worth area, my turfgrass colleague, Dr. Lindsey Hoffman, and I have gotten many calls this week from concerned lawn owners, schools and the media.

Challenges to implementing IPM too great for most maize farmers in Mexico

Yet IPM is not widely used to manage pests in the crop. In a peer-reviewed article in the Journal of Integrated Pest Management in 2014, researchers from Mexico examined pest complexes in maize and the challenges with adoption of IPM programs.

It’s time to scout peanuts in Georgia

In Southeast Farm Press

by Mark Abney, University of Georgia entomologist

Spider mites have been reported on a number of crops including vegetables and cotton since this spring, and as conditions continue to be hot and dry in many locations, we are beginning to see populations jump in peanut.

The two spotted spider mite is a challenging pest to control. It thrives in hot, dry conditions where it completes development in as little as seven days at 81 F. Female mites can lay up to 100 eggs over several weeks, so it is easy to see how infestations can go from light to heavy in a very short period of time.

Mixed worm populations starting in Virginia and the Carolinas

By Ames Herbert, Virginia Extension Entomologist

In Southeast Farm Press

Mixed worm populations are reportedly increasing in both South Carolina and North Carolina peanut crops.

These populations include the corn earworm (may be some tobacco budworm also, but you cannot tell these species apart without some experience and good magnification of the mandibles/jaws), beet armyworm, and fall armyworm.

For more than 20 years, specialists with the University of Kentucky Integrated Pest Management Program have trapped moths of Kentucky’s major agricultural pests to give producers an early warning about potential outbreaks. A recent UK College of Agriculture survey shows this program is paying financial and environmental dividends for the agricultural industry.
